Working Principle

The TLE2082 is a four-stage op-amp based on the classic ACPG (amplified common propagation gain) design which is the basis for many operational amplifiers. The principle of operation is straightforward: the input signals are applied to the pair of differential amplifiers, whose outputs are then further amplified and filtered. The output of the amplifier is then applied to the gain control circuitry, and a feedback path is also established between the output and the differential amplifier stages. The output from the gain control circuitry is then used to fine-tune or adjust the gain of the amplifier.

The result is an amplifier with excellent linearity, low noise, and good gain accuracy over a wide range of frequencies. The TLE2082 has a wide gain range, a low noise floor, no phase shift, and a low input bias current. These features make it an ideal choice for a variety of applications in the medical, test and measurement, power control and audio fields.
